PURPOSE:To obtain a transistor element by utilizing redox potential difference by depositing, bonding and joining second and third electron transport proteins having different redox potential to each other onto a first electron transport protein. CONSTITUTION:A solution of flavodoxin 18 is dropped onto the surface of water to form a monomolecular film, and a glass plate 16 on which a parallel electrode 17 is shaped is sunk and the film 18 is attached and joined. A parallel electrode 20 is shaped at a right angle to the electrode 17 at a low temperature, and a monomolecular film 19 of cytochrome C formed through the same method is annexed and joined. Likewise, a flavoxin monomolecular film 21 is attached onto the film 19 and a parallel electrode 22 at a right angle to the electrode 20. When lipid or a fatty acid is mixed previously to an electron transport protein solution dropped onto the surface of water, protein molecules are supported, and orientation is aligned. When the electrodes 17, 20, 22 are chemically decorated previously by 4, 4'-piperidine, etc., electrons are transferred excellently between protein films. When voltage V1, V2 is applied to the element according to a predetermined method, redox potential changes in the same manner as a PNP junction, thus acquiring a transistor at a molecular level. |
